I want both the 28 and the 50. the 28 for wideangle, and the 50 to use as a standard lens. i know that primes give better contrast and sharpness than zooms and so i would like to use them for non-point-and-shoot photography. however i also realise that for the all the downsides zoom are tremendously useful. in the past though I have bought poor qaulity zoom (canon 28-90 and 80-210), which suited me fine in terms of focal range but were severely lackign in terms of optical quality.

this help?

is the canon 28-105 USM 3.5 any good? its in my price and focal range?
